[0030] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention can be combined with each other.

[0031] Currently, welding compressor screws to the chassis of heat pumps or air conditioners primarily involves welding each screw individually, selecting the appropriate specifications based on customer needs or selecting similar screws due to industry standards issues. However, this welding method, when the compressor screw specifications are appropriate, simply presses down on the bottom of the screw. This welding method can cause the screw to tilt or the top of the polished screw to extend beyond the reference surface due to variations in pressure. Furthermore, due to variations in compressor screw specifications and chassis thickness, manual welding cannot precisely achieve the desired dimensions.

[0032] Based on this, see Figure 1 and Figure 2 The welding fixture 1000 provided in the embodiments of the present invention can effectively alleviate the aforementioned technical problems. The welding fixture 1000 is capable of welding multiple screws simultaneously. Furthermore, when welding the chassis to the multiple screws, the weld height of the multiple screws is ensured to be consistent, thereby improving machining accuracy.

[0033] Figure 1 A schematic diagram of a welding tool 1000 provided in an embodiment of the present utility model; Figure 2 This is an exploded schematic diagram of the welding tool 1000 provided in an embodiment of the present invention, as shown in FIG. Figure 1 and Figure 2As shown, the welding fixture 1000 in this embodiment includes a limit plate 100 and multiple adjustment members 200. The limit plate 100 is provided with multiple adjustment holes 110 and multiple screw fixing holes 120. The screw fixing holes 120 are used to place the screws to be welded to the chassis. The multiple adjustment members 200 are arranged in a one-to-one correspondence with the multiple adjustment holes 110. The end of each adjustment member 200 away from the limit plate 100 is used to be fixedly connected to the chassis. The multiple adjustment members 200 can be used to adjust the distance between the limit plate 100 and the chassis. By providing multiple screw fixing holes 120, the fixture can weld multiple screws simultaneously. Moreover, because they are set on the same limit plate 100, when welding screws, multiple compressor screws can be limited simultaneously, so that each screw has a consistent height from the chassis. By providing the adjustment members 200, the distance between the limit plate 100 and the chassis can be adjusted, making it suitable for welding various types of screws. The multiple adjustment members 200 can be adjusted to the same horizontal height to ensure that the limit plate 100 and the base plate are parallel to each other, thereby ensuring that the welding heights of the multiple screws are consistent when the chassis is welded to the multiple screws, thereby improving processing accuracy.

[0034] In detail, because the bottom of the mold sheet metal chassis is uneven, the flatness can be ensured by adjusting the height of multiple adjustment parts 200. In addition, after the compressor screw is inserted into the screw fixing hole 120, the penetration distance is no longer entirely determined by the chassis and the compressor screw base. Instead, it is limited by the limit plate 100 of the welding fixture 1000, thereby achieving precise control of the distance between the top of the compressor screw rod and the chassis. Moreover, when the screw size has a deviation of ≤2mm, the welding fixture 1000 can fill the gap between the boss 214 below the compressor screw and the chassis with solder due to the action of the limit plate 100, and welding can be completed without the need to purchase more non-standard screws for welding.

[0035] To ensure that the adjusting member 200 does not move up and down relative to the limiting plate 100 during welding, the welding fixture 1000 in this embodiment also includes multiple locking members 400. Each adjusting member 200 is secured to the limiting plate 100 via at least one locking member 400. In this embodiment, the locking members 400 are flange nuts. Of course, the locking members 400 can also be other retaining structures, as long as they ensure a secure connection between the adjusting member 200 and the limiting plate 100. This is not a limitation here.

[0036] Specifically, see Figure 1 and Figure 2 , and combined with Figure 3, each adjusting member 200 provided in this embodiment includes a first screw 210 and a second screw 220, the first screw 210 and the second screw 220 are threadedly connected, and the first screw 210 is inserted into the corresponding adjusting hole 110. The first screw 210 and the second screw 220 can rotate relative to each other to adjust the height of the entire adjusting member 200, and then adjust the distance between the limiting plate 100 and the chassis. In detail, the first screw 210 in this embodiment includes a first screw body 211 and an intermediate stud 212, the first screw body 211 is provided with a groove 213, the intermediate stud 212 is arranged in the groove 213, and is connected to the first screw body 211; the intermediate stud 212 is provided with a first external thread 2121, and the second screw 220 is provided with an internal thread, and the first external thread 2121 cooperates with the internal thread of the second screw 220. In order to facilitate observation and adjustment of the height of each adjusting member 200 and ensure that multiple adjusting members 200 can be quickly adjusted to the same height, the outer surface of the second screw 220 in this embodiment is provided with a scale.

[0037] In order to facilitate the fixing of the first screw rod 210 and the limiting plate 100, please continue to refer to Figure 1 and Figure 2 , and combined with Figure 3 , Figure 3 This is a schematic diagram of the first screw 210 provided in an embodiment of the present invention. In this embodiment, a boss 214 is provided on one end of the first screw body 211 near the second screw 220; a second external thread 2111 is provided on the surface of the first screw body 211. The first screw 210 is inserted into the adjustment hole 110, and the boss 214 abuts against the surface of the limit plate 100 near the second screw 220. After the first and second screws 210, 220 are rotated and adjusted to the desired height, the flange nut engages with the second external thread 2111 of the first screw body 211 to lock the limit plate 100, preventing it from moving relative to the first screw 210.

[0038] Alternatively, the first screw rod 210 may be provided with an internal thread, the second screw rod 220 may be provided with a mating external thread, and a scale may be provided on the surface of the first screw rod 210 to facilitate adjustment and observation of the height adjustment. The adjustment member 200 may also be designed as other structures for adjusting the height of the limit plate 100, depending on actual circumstances and not limited herein.

[0039] To enhance the versatility of the welding fixture 1000 and accommodate various chassis and screw welding applications, each adjustment hole 110 in this embodiment is a strip-shaped hole, and the adjustment member 200 is movable along the extension direction of the adjustment hole 110. Each screw fixing hole 120 is a strip-shaped hole, and the screw to be welded to the chassis can be movable along the extension direction of the screw fixing hole 120. The position of the adjustment member 200 within the adjustment hole 110 can be adjusted according to the size of the chassis to facilitate the fixing of various chassis types. The position of the screw within the screw fixing hole 120 can also be adjusted according to the size of the chassis to accommodate various screw welding applications.

[0040] Specifically, see Figure 1 and Figure 2 The limiting plate 100 in this embodiment is in the shape of a disc, and the adjustment hole 110 includes a first adjustment hole 111 and a second adjustment hole 112, and the first adjustment hole 111 and the second adjustment hole 112 are arranged at intervals along the radial direction of the disc; the number of the first adjustment hole 111 and the second adjustment hole 112 are both multiple, and the multiple first adjustment holes 111 are arranged at intervals along the circumference of the disc, and the multiple second adjustment holes 112 are arranged at intervals along the circumference of the disc. The multiple screw fixing holes 120 in this embodiment are also arranged at intervals along the circumference, and the screw fixing holes 120 are also strip-shaped holes and extend radially. Of course, the limiting plate 100 can also be designed as a square, rectangular, pentagonal or other structure, which is not limited here. The number, position and extension direction of the adjustment holes 110 and the screw fixing holes 120 are determined according to the specific welding situation and are not limited here.

[0041] In order to facilitate the connection between the welding fixture 1000 and the chassis, the end of the adjusting member 200 in this embodiment away from the limiting plate 100 is provided with a magnetic member 300, and the adjusting member 200 is magnetically connected to the chassis via the magnetic member 300. The magnetic member 300 in this embodiment is a magnetic ring sleeve. Of course, the magnetic ring sleeve can also be replaced with a magnet or other structure, which is not limited here. In addition, a clamping structure can also be provided to achieve a fixed connection between the adjusting member 200 and the chassis, which is not limited here.
